Criteria

Inclusion Criteria:

Subject must be 18 to 45 years of age (inclusive).

Subject must be a healthy male or female volunteer (i.e., hematology, coagulation, clinical chemistries and urinalysis tests must be within study-defined ranges (See Appendix B). Clinical tests must be performed within 28 days of receiving first dose of study drug.

Body Mass Index (BMI) must be between 18 and 30 kg/m2 inclusive.

Subject must be Tuberculin Skin Test/Purified Protein Derivative (TST/PPD) negative (within the previous 1 year) at Screening. The TST/PPD may be omitted if the subject presents written evidence of having a negative test during the previous 12 months.

Subject must be able to give voluntary written informed consent before any study related procedure is performed.

If female, has no childbearing potential or agrees to avoid becoming pregnant from the day of screening through their entire participation in the trial (Day 28) by using one of the following acceptable methods of birth control plus recommended use of a barrier method (condom) by the male partner (even if vasectomized):

intrauterine contraceptive device; or

diaphragm in combination with contraceptive jelly, cream, or foam; or

spermicide; or

abstinence. Non-childbearing potential is defined as being post-menopausal for at least 2 years, status after bilateral tubal ligation for at least 1 year, status after bilateral oophorectomy or status after hysterectomy.

Hormonal contraceptives of any type or form (including oral, transdermal, vaginal or depot preparations) will not be allowed during the study.

All female subjects of childbearing potential must have a negative serum pregnancy test at screening and within 24 hours of the first dose of study product.

Male subjects must agree to use an acceptable barrier method for birth control (abstinence or use of a condom with spermicide) from screening through Study Day 28 and advice and recommend use of additional birth control (as in criterion 6 above) to female sex partners throughout the study.

Subject agrees not to donate blood during the study and up to 30 days after Study Day 28.

Subject agrees to comply with all study requirements, including clinic house rules.

Exclusion Criteria:

A history of clinically significant gastrointestinal, renal, hepatic, neurologic, hematologic, endocrine, oncologic, pulmonary, immunologic, psychiatric, or cardiovascular disease or any other condition which, in the opinion of the Principal Investigator (PI), would jeopardize the safety of the subject or impact the validity of the study results.

Subject has been on an abnormal diet during the 4 weeks preceding the study. Abnormal diet is defined as a diet in which the subject has a significant change in eating habits (e.g., liquid diet only) and an unbalanced diet (e.g., protein only, high fat, low carbohydrate, etc.).

Subject has received an investigational drug in a clinical trial within 30 days prior to study initiation.

Subject has used any OTC medication, including vitamins and herbal supplements, within 7 days prior to Day 1 of the study, unless in the opinion of the PI, the substance would not likely impact on the conduct of this study, including PK of SQ109.

Subject has used any prescription medication within 14 days prior to Day 1 of the study, or the use of hormonal preparations containing sex hormones within 30 days prior to Day 1 of the study.

Subject has any current medical condition requiring treatment with medication, either prescription or OTC.

Subject has been treated with any known CYP450 enzyme altering drugs such as azoles, antifungals, barbiturates, phenothiazines, cimetidine, carbamazepine, etc., within 30 days prior to Day 1 of the study.
